I also build trolls at the end. (they are good vs cav and swordsmen and buildings and you can also spam monsters more consistenly when you have industry and scavenger, thats why they got these strong powers, because goblins and mordor have lots of expensive monsters, isen can spam upgraded inf and cav with it like in movie) made use of every normal unit mordor has to offer. thats how its supposed to be played, if game would have progressed I would have added troll pit units and a mumakil to the army.
